  Client

SYNOPSIS

   C_RFC3315_18_1_2_CnfRetransMRT.seq [-tooloption...] 
  -pkt   C_RFC3315_18_1_2_CnfRetransMRT.def

INITIALIZATION

• Network Topology

          NUT(Client)
          |           
          |                        
Link0   --+--------+------------------------ 3ffe:501:ffff:100::/64
                   |
                   |          
                   TN(Server) 
   

• Verification Points



   The client transmits the message using the following parameters:
     IRT   CNF_TIMEOUT  

     MRT   CNF_MAX_RT   

     MRC   0            

     MRD   CNF_MAX_RD   

   RT for each transmission is based on the previous value of RT: 

     RT = 2*RTprev + RAND*RTprev. 

   If (RT > MRT) 

     RT = MRT + RAND*MRT.

TEST PROCEDURE

       NUT      TN
        |       | 
        |       |Initialize NUT(as a DHCPv6 client)
        |       |
        | ----> |Solicit 
        | <---- |Advertise 
        | ----> |Request 
        | <---- |Reply

        | <---- |Echo Request
        | ----> |Echo Reply
        |       |	 
        |       |Restart NUT (or Interface down/up)
        |       |
        | ----> |Confirm
        |       |
        .       .Waiting for retransmission until RT = MRT + RAND*MRT
        |       |
        | ----> |Confirm (8*)
        |       |

JUDGEMENT

  (8*)PASS: TN receives retransmitted Confirm.
            And RT conforms to Verification Points.

TERMINATION

  N/A
